Finding
Coverage: the online research-infrastructure beyond the core corpus adds no John Gurney record
Beyond the FamilySearch, Internet Archive, and Google corpus already worked, the specialist online research infrastructure returns no John Gurney and no Gurn-variant in the emigrant or early-settlement window: Coldham's three Ancestry emigrant compilations (Admiralty adventurers, bonded emigrants, Christ's Hospital apprentices), the Congregational Library's colonial-church index, and the Massachusetts Digital Commonwealth aggregator are each negative or out of window. This bounds the 'immigrant of unknown origin' state to the present reach of the online infrastructure; the one compilation of its class not yet reached is Coldham's Complete Book of Emigrants, 1607-1660 (absent from Ancestry), which with TNA E 157/20 remains the outstanding emigrant-record residual (lead L-170).
Why this conclusion
- Supported by Negative result Negative: no Gurney emigrant in Coldham's English Adventurers & Emigrants 1609-1660This documented database/index negative supports the synthesized coverage conclusion for the modern research infrastructure.
- Supported by Negative result Negative: no Gurney transportee in Emigrants in Bondage 1614-1775 within the emigrant windowThis documented database/index negative supports the synthesized coverage conclusion for the modern research infrastructure.
- Supported by Negative result Negative: no window-era Gurney in Christ's Hospital child-apprentice emigrantsThis documented database/index negative supports the synthesized coverage conclusion for the modern research infrastructure.
- Supported by Negative result Negative: New England's Hidden Histories holds no pre-1690 church record for John's townsThis documented database/index negative supports the synthesized coverage conclusion for the modern research infrastructure.
- Supported by Negative result Negative: Digital Commonwealth returns zero 'Gurney Braintree'This documented database/index negative supports the synthesized coverage conclusion for the modern research infrastructure.
Related context
- Provides context for Negative result Negative: no record states John's English originThe exhaustion of the modern online research infrastructure contextualizes the record-coverage negative that no surviving record states John's English origin (g13-colonial-record-coverage): the online layer beyond the core corpus has now also been searched without result.
- Context from Analysis Analysis: the open program reconciled to the leads catalogueThe emigrant-record residual homed in g13-research-source-coverage is one of the record-location residuals the reconciliation places outside this topic; it contextualizes the origin strand of the open program.
- Context from Negative result The London port-emigration lists and the livery-company registers, searched for John Gurney's crossing and trade, return no emigrant John Gurney. Hotten's Original Lists (behind them TNA E 157/20) hold no Gurney passenger in any spelling; a ROLLCO all-company livery sweep finds no East-Anglian Gurney apprentice, the sole provincial tailoring-Gurney being the eliminated Buckinghamshire Candidate-A family.The Hotten and ROLLCO negative searches extend the online/source-coverage map beyond the earlier infrastructure negatives and show why the remaining origin state is still a bounded negative rather than an unsearched gap.
